how many balls can you carry? all of them?

drive - ball capacity etc...
The hopper can hold around 50, although once we stick more than 20 in there, we have issues with the polycarb deflecting, and balls wedging on top of the funnel in the bottom, causing jams. Hopefully we'll have a fix figured out shortly, for SVR.

The drivetrain started with 2 FP's and 2 small CIM's, but moved to 2 CIM's only once we had a boatload of problems with the FP's. We decided we'd be better off removing them and regaining the weight for the rear roller on our frame which allows us to drive up the ramp backwards, and keep us from riding up on any balls. We knew we wouldn't be winning many pushing matches to start with, so we're fine with the tradeoff.

Our front roller picks up balls and delivers them to the hopper, as well as rolling them out into the side goals when reversed.

The rear set of conveyors delivers the ball through the back shell of the robot up to the shooter. We planned on having an aimer on the shooter hood, to adjust the angle at which the ball leaves the shooting wheel, but due to time constraints when we shipped it, it wasn't working. We also found out we didn't have the weight for it once we got to Portland. We may or may not have it back on the robot come SVR.

The shooter itself uses 2 CIM's powering a custom machined, perimeter weighted ABS wheel. By sacrificing two CIM's in the drivetrain, we were able to ensure that the shooter doesn't slow down enough to make a difference between shots.
